Note
I have since learned that both Black-horned and Forbes' could have this coloring. However, after work by researchers who analyzed songs of tree crickets in multiple states, it is now generally accepted that greenish tree crickets with dark on the antennae, head, pronotum and/or limbs - that are west of Ohio - are Forbes' tree crickets instead of Black-horned.

(This much black rules out Prairie tree cricket)

Beautiful photo of a male O. forbesi or O. nigricornis
Unfortunately, it is not possible to separate Black-horned tree crickets from Forbes' tree crickets from photos alone.
